Introduction: The DWS-295F sodium ion meter is a conventional laboratory analysis instrument, which is mainly used for laboratory determination of sodium ion concentration in water samples and water sample temperature (such as steam condensate, desalinated water, boiler feed water, etc.), and It can be used in universities, scientific research institutions, petrochemical industry, microelectronics and other departments to determine the concentration of sodium ions in natural water, boiler feed water, industrial drainage and other water. Features: 1. With automatic temperature compensation, automatic calibration, automatic calculation of the electrode's percent theoretical slope and other functions. 2. With power-off protection function, the measurement data and set parameters stored in the instrument will not be lost after power-off. 3. The instrument has the functions of storing, deleting, consulting, printing and maintaining the measurement results. The instrument can store 50 sets of pNa, mV or sodium ion concentration measurement experimental data, and provides two sets of printing modes for users to choose. 4. The instrument uses a three-electrode measurement system with dual display of pNa value and temperature value, mV value and temperature value or sodium ion concentration value and temperature value. 5. The instrument has a USB interface, which can communicate with the computer. Technical Parameters: Model: DWS-295F sodium ion meter Instrument level: 0.01 Measurement parameters: pNa value, mV value, Na+ concentration, temperature value pNa value: (0.00～9.00) pNa mV value: (-1999～1999) mV [Na+] ion concentration: (2.3×10-2～2.3×107) μg/L Temperature value: (-5.0～110.0)℃ pNa value: ±0.01pNa Calculation error of pNa value ~ [Na+] value conversion: ±1% (reading) Temperature value: ±0.2℃ Power supply: DC universal power supply (9V, 800mA, internal positive, external negative) Dimensions (mm); Weight (kg): 280×215×92; 1
